IMPROVEMENT IN MACHINES FOR POLISHING SHOW-CASE FRAMES- Specificationforming part of Letters Patent No. 154,901, dated September 8, 1874;application filed July 27, 1874.

To all whom 'it may concern:

Be it known that I, F. POLLARD, of Cleve- I land, in the county ofGuyahoga and State of Ohio, have invented certain newand usefulImprovements in Machines for Polishing Show-Case Frames and I do herebydeclare that the following is a full, clear, and exact construction andarrangement of a machine for polishing show-cases, including a truck forcarrying the show-cases to and from the machine and holding them whilebeing polished, as will be hereinafter more fully set forth.

In' order to enable others skilled in the art to which my inventionappertains to make and-use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichFigure l is a side elevation of my entire machine, and Fig. 2.is atransverse vertical section of the truck. 7

A A represent two upright parallel posts or standards, between which arepivoted two joists, B B, connected by cross-bars at O O. The joists Band cross-barsO form a tapering frame, wider at the inner thanat-th'eouter end. Across the inner end of the frame in suitable boxes isa shaft, a, provided, on one end, with a crank, D, and on this shaft,within the frame, is a Wheel, E, connected by a cord or belt, I), with apulley, d, on a shaft, 0, across the front end of the frame. On one endof this shaft is the polishing-wheel Gr, composed of a number of roundpieces of Woolen cloth or other suitable material firmly fasten edbetween washers or disks on the shaft. The frame B O, with thepolishing-wheel, is, by means of a cord, h, and pulley f, raised andlowered and suspended at anyv height desired from the floor. The truckis composed of a frame, H, provided with three sets or pairs of Wheels,the center set, m, being larger and lower than the end pairs, n, so thatthe truck will always rest and move 'on' the center set and one end setof the wheels, it being easily tipped to either end, as required. Theend pieces of the truck-frame are arched or elevated in the center, andbetween their highest central points is pivoted a platform, J, which maybe turned to either side, and rest upon the side rails of the frame. Oneach side edge of the platform J are flanges p p, to support theshow-case, and in the top rails of the platform are projecting points xw, to stick in the bottom of the show-case to prevent it from slidingoff the truck when it is tipped either way, so that it requires no timeto fasten the show-case to the truck. The show-case is laid lengthwiseacross the truck when the ends are being polished.

The truck will carry a case any length desired, and a boy can,unassisted, run it under the wheel at any angle required, so as to bringany and every part of all the moldings of which the showcase is made incontact with the wheel.

The machine thus constructed will save a vast amount of time, labor, andexpense, and at the same time do the work better than it can be done byhand.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the tilting-frame J and truck-frame H, for holdingand adjusting the show-case While the metal part thereof is beingpolished, substantially as set forth.

2. 'In combination with the tilting-frame J and truck-frame H, themoving frame B G, having shafts a 0, wheels E d, belt b, polishing-wheelG, and adjusting-cord h, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
